Abstract: Ultraviolet irradiation of liquids for purposes of sterilization, disinfection, cleaning and/or treatment. A liquid collection reservoir can receive an inflow of a liquid. A filtering unit can filter the inflow of liquid received by the liquid collection reservoir. A liquid chamber stores the liquid. Ultraviolet light emitting sources located about the liquid chamber irradiate the liquid in the liquid chamber with ultraviolet light. A control unit, operatively coupled to the ultraviolet light emitting sources, controls the irradiation of the liquid in the liquid chamber with the ultraviolet light emitting sources. The control unit is configured to control an intensity and a duration of the irradiation as a function of time that the liquid is stored in the liquid chamber and the amount of the liquid that is in the liquid chamber.

Abstract: Ultraviolet radiation is directed within an area. Items located within the area and/or one or more conditions of the area are monitored over a period of time. Based on the monitoring, ultraviolet radiation sources are controlled by adjusting a direction, an intensity, a pattern, and/or a spectral power of the ultraviolet radiation generated by the ultraviolet radiation source. Adjustments to the ultraviolet radiation source(s) can correspond to one of a plurality of selectable operating configurations including a storage life preservation operating configuration, a disinfection operating configuration, and an ethylene decomposition operating configuration.
